Best B2B Data Providers in 2026

ZoomInfo is the largest publicly listed vendor in the category. Its homepage describes verified data on more than 500 million contacts and 100 million companies. The company trades on Nasdaq under the ticker GTM and reported GAAP revenue of US$1,249.5 million for the 2025 fiscal year, an increase of 3% on the previous year. Sales packages are sold as ZoomInfo Professional, Copilot Advanced and Copilot Enterprise, alongside separate marketing packages (Marketing Demand, ABM Lite, ABM Enterprise). No prices are published; the pricing page states that cost depends on features, the number of licences and credit usage. The platform also bundles intent signals and workflow tools, so buyers who only need contact lookups typically pay for capabilities they do not use.

Dun & Bradstreet is the oldest provider on this list; its newsroom states that companies have relied on it since 1841. Its core asset is the D-U-N-S Number, a business identifier that, according to the company, more than 600 million companies worldwide use. The D-U-N-S system makes the firm a common reference layer for credit, supplier and compliance processes as well as for sales and marketing data, sold through products such as D&B Hoovers. On 26 August 2025 the private equity firm Clearlake Capital completed its acquisition of Dun & Bradstreet at US$9.15 per share in cash, taking the company private. Pricing for its data products is not published.

Apollo.io combines a contact and company database with outreach tooling such as email sequencing and a dialer. The company states that it covers more than 240 million contacts and 30 million companies, and that over 600,000 companies use the product. Its pricing page lists Free, Basic, Professional and Custom plans and describes the Free plan as staying free with no time limit; credits are pooled across a team and do not roll over. An Apollo-published comparison dated May 2026 gives annual-billing prices of US$49 per user per month for Basic and US$79 for Professional. Because data and engagement tools are sold together, Apollo is frequently used by small teams as a single outbound system.

It reports coverage of more than 600 million companies in over 200 countries, sourced through direct connections to more than 400 government registries.

The company lists its headquarters in Northampton, with a North American entity in Delaware and an engineering office in Chișinău. A free trial is offered; plan prices are not listed on the homepage.

Cognism sells contact and company data for sales prospecting. Its pricing page lists two prospecting tiers, Standard and Pro, each including five seats. Standard covers contact and company data, list building with firmographic, technographic and signal filters, AI account research, API and MCP access, and CSV export and enrichment; Pro adds higher-quality mobile data, on-demand mobile verification and intent data. CRM Enrichment is available as an add-on or standalone product, and a Data-as-a-Service option is also offered. Pricing is quote-based, with one credit used per revealed contact.

Lusha lists SOC 2 Type II, ISO 27701 and ISO/IEC 42001 certifications on its homepage. Unlike many competitors, it publishes prices: a free plan with up to 40 credits per month, Starter at US$49.90 per month (US$37.45 billed annually) with 400 monthly credits, Professional at US$69.90 (US$52.45 annually) with 600 credits, and Premium at US$399.90 (US$299.95 annually) with 3,400 credits; a Scale plan is priced by quote.

Seamless.AI describes itself as a real-time search engine that crawls the web to find and verify contact information at the time of a search. The company cites more than 1.8 billion verified business emails and 414 million phone numbers. A free plan includes 50 credits with no credit card required; paid pricing is not fixed and is quoted according to the number of licences, credits and features required. The real-time model is positioned as an alternative to static databases, although the homepage does not explain how much of its data is stored versus retrieved live.

UpLead sells verified emails and mobile direct dials on a credit basis, where one credit unlocks a contact for download or CRM export. Its pricing page lists a seven-day free trial with five credits; Essentials at US$99 per month (US$74 per month billed annually) with 170 monthly credits; Plus at US$199 per month (US$149 annually) with 400 monthly credits; and a Professional plan, sold annually with custom seats and credits. Additional credits cost US$0.60 on Essentials and US$0.50 on Plus. The plan structure makes the per-contact cost easy to calculate in advance.

People Data Labs sells person and company data primarily to developers and data teams building their own products, rather than through a prospecting interface. Its pricing page lists a free tier with up to 100 credits per month, in which email, phone and address fields are obfuscated; a Pro tier starting at US$98 per month with as few as 350 credits; and Enterprise contracts with custom pricing and annual terms. Annual commitments carry a 20% discount, and volume discounts apply as usage grows. The model suits companies embedding B2B data in software, but it requires engineering work to use.

Kaspr is a Paris-based prospecting tool launched at the end of 2018 and acquired by Cognism on 27 April 2022. It continues to sell under its own brand and pricing. The free plan includes 15 B2B email, 5 phone and 5 direct-email credits per month. Paid tiers are listed per user per month in euros, pounds and dollars: Starter at US$49 or US$65 and Business at US$79 or US$99 depending on billing term, with unlimited B2B email credits and capped phone credits; an Enterprise plan is priced by quote. The product is commonly used alongside LinkedIn to reveal contact details for profiles being viewed.

TargetWise is a B2B contact-data service that finds work email addresses and business phone numbers by querying around 15 data providers in a single search, rather than relying on one proprietary database.

It is aimed at sales, marketing, recruitment and market-research teams, and at AI products that need business contact data. Access is through a web app, a REST API and an MCP server for AI agents and automation tools. Pricing is pay-as-you-go at US$0.09 per work email and US$0.18 per business phone number, with a US$100 minimum top-up and a monthly free allowance of 20 emails and 5 phone numbers.
